Well my gf and I are 50+ turns into a co-op game to get used to your factions (on my "faster game" mod btw), she being the Terrans and I, Big Bro. We're both trying out ICS (I've messed with it a few times now), and while I would normally be rather ahead of her, she was ahead of me, using a pretty close equivalent to Democratic/Planned + the automatic Creches to pop boom. She also only had about 5 ground formers by then, and maybe a couple sea. We've each warred a bit here and there early on, both on our own continents with 2 dwarf computers each. Not the best of circumstances, but we're waaay beyond winning at this point, being on Librarian, having most of lv4 tech, just got air power and tree farm, and the faction we haven't mapped at all is Deidre.
So basically, I had a hard time getting research going, with the 150 tech cost, but now I'm rivaling her 4-5 turn techs. I do enjoy making trance 1-1-1's with bonus 2x police. She does have some drone (police) difficulties and has been implementing Virtual World. Remember your Terran stats are basically cancelled out by your high talent # and your creches, leaving you with mostly a +2 growth. Also, a new hitler? lol > >. I would consider giving them -1 growth to counteract the easy popboom. To counteract the -5 interest (there wasn't any -econ, right?), she simply spent her money often on partial-hurrying things (as in fully hurrying but letting the minerals do some of the work).
Big Bro feels like a bit of a struggle, and I don't feel like sharetech/techshare is going to do a thing against AI, at least. I made sure to go for Planetary Energy Grid to give myself more focus to money at least. The +1 Ind was kinda nice, and the +1 probe has had little use to me against AI as well, especially since the one time I was going to probe my subservient UofP pact bro for a tech I was "milking," he gave it to me since I had given him like 3 techs before to direct his research. As a side note, he's even built roads between my bases lol =P.
As for your Transcend suggestion, I somehow doubt it'd make such a difference to the Arians. The Creches solve most problems plus giving +2 growth, starting with Democracy affects you mainly with its +2 growth, and forests are your friend. I can't say for sure unless I play an unmodded version, of course. In transcend, I suspect it's easy to die with many factions if you're not careful and you start near an aggressive faction. Random things happen, so make sure you aren't judging too quickly.
